"ScreenFlow is recognized by the industry as the premier screen recording and editing application for the Mac," said Barbara DeHart, vice president of marketing at Telestream. "With ScreenFlow 4 we`ve worked hard to take advantage of the latest advancements on the Mac platform with our support for Retina displays and 64-bit technology. We`re helping users easily meet regulatory requirements with closed caption support, and we`re allowing them to create more compelling content with the new chroma key capability. Users can now do it all with ScreenFlow 4."

Powerful organizational toolsScreenFlow 4 adds important new features to help users keep complex projects organized. Nested clips allows users to merge multiple elements into a single clip on the timeline, making it easier to access and edit content and apply filters and video actions. New media library organization tools make it easier for users to find and organize all the clips in their libraries, search for a specific clip, arrange clips by name, duration or type, and more.

"ScreenFlow 4 is a serious power upgrade in terms of speed, stability and features," said Marty Smith at ComboCasting.com. "My favorite feature is nested clips, which not only allows me to streamline my projects, but adds a completely new dimension for special effects; limited only by my creativity. ScreenFlow remains the most used app on my Macs, and the upgrade to version 4 is absolutely a no-brainer."

More razzle-dazzle production featuresWith ScreenFlow 4, Telestream adds more professional production tools that enable users to add sparkle to any video. Built-in chroma key allows users to replace a green (or any color) background with a custom video or still image background, adding a professional look to video productions. New Core Image video effects filters include advanced color adjustments, distortion effects, blurring, alpha mask, color effects and more. New Core Image audio effects filters include EQ, multiband compression, peak limiting, delay and more. Freehand callout support for all media and ProRes Alpha Channel export support are now available. Plus, full color-sync-enabled rendering provides increased fidelity of preview and exported videos.

"The full-screen Retina recording quality in ScreenFlow 4 is truly impressive," said Don McAllister at ScreenCastsOnline.com. "As someone who makes screencasts for a living, I need ultra-high quality, full-screen recording that doesn't eat up all my disk space. ScreenFlow 4, with its 64-bit technology, is faster and higher quality than ever. With the amazing quality, and streamlined editing, the upgrade to ScreenFlow 4 makes my workflow so much faster."

Tools to reach new audiencesThe addition of closed captions and new export options in ScreenFlow 4 makes it easy to target and reach new audiences. Users can now add, edit and publish ADA (American Disabilities Act) compliant soft subtitles as caption tracks to MPEG-4 movies and YouTube videos. Captions can also be created in multiple languages. MPEG-4 export using the x264 video codec allows for the distribution of exceptionally high-quality video to a greater number of viewing devices.

Features to save time and streamline workflowsA number of new shortcuts ? including JKL keystrokes for Rewind, Stop, Playback, and the ability to start and end transitions in one click ? make ScreenFlow 4 more intuitive and streamlined. The Dynamic Update feature offers the ability to automatically reload media that has been modified in another application, saving time and disk space. The new recording timer lets users set a time for recording to stop, which allows them to set up a recording and return to it later.

"ScreenFlow 4 provides huge time savings," said Veit Irtenkauf, CEO and co-founder of Digital Dazzle, LLC. "The Dynamic Updating of Media feature alone saves us hours and hours whenever we make changes. With this new feature, we can make last-minute changes to images with a single click. Previously, we had to change the media outside of ScreenFlow, re-render it, bring in the new image and re-do all the animation in the timeline. Given the elaborate editing we do, this feature is worth hundreds of dollars to us in every single project."
